24 Technical Notebook WATERPROOFING TERRACES AND BALCONIES mortar (used to partially replace the mixing water). The masonry may also be evened out using PLANITOP FAST 330, quick-setting, fibre- reinforced cementitious mortar for evening out irregularities from 3 to 30 mm on uneven substrates. Once this layer has dried, bond MAPEBAND to the substrate as follows: • Apply an even coat of the waterproofing product chosen (see section 4) with a smooth trowel on the clean, dry substrate. • Lay MAPEBAND by pressing along the sides, making sure there are no creases or air bubbles. • Lay another layer of the waterproofing product fresh on fresh to completely cover the sides of the tape. In the corners, use the special components from the MAPEBAND range (90° ANGLES and 270° ANGLES), while the joints between the strips and special pieces must be made using a double-buttering polychloroprenic contact adhesive in solvent such as ADESILEx LP. Apply MAPEBAND on the control joints in the substrate using the same technique as described above, making sure the strips are turned towards the inside of the joint in an upside-down “Ω” shape. The structural joints must be waterproofed by bonding MAPEBAND TPE 1.2 mm thick tape with borders reinforced with polyester fabric. Bond in position using ADESILEx PG4 two-component thixotropic epoxy adhesive as follows • Apply an even layer (Fig. 5.14) approximately 1-2 mm thick of ADESILEx PG4 with a smooth trowel on the clean, dry substrate. Try to avoid the adhesive running into the joint.

Press down along the sides, making sure there are no creases or air bubbles (Fig. 5.15). • Apply a second layer of ADESILEx PG4 fresh on fresh, and completely cover the sides of the tape with the second coat (Fig. 5.16). • Smooth over the surface with a flat trowel and, while the product is still fresh, sprinkle on a layer of 0.5 spheroid quartz (Fig. 5.17) to create a substrate which is rough enough to form a good bond with the waterproofing product. • Once the curing process of the ADESILEx PG4 has been completed, remove any loose quartz (Fig. 5.18). The joints between the strips of MAPEBAND TPE may be made with a hot- air welding gun or by cold welding by overlapping the TPE part by at least 5 cm and bonding them together with a double-buttering polychloroprenic contact adhesive in solvent such as ADESILEx LP. We recommend laying the MAPEBAND TPE inside the joint to form an upside-down “Ω” shape. After waterproofing and sealing the interruptions and critical points as described above, apply the waterproofing product chosen. FOR TWO-COMPONENT PRODUCTS Mixing of MAPELASTIC or MAPELASTIC SMART is carried out by pouring component B (liquid) into a suitable clean container and slowly adding component A (powder) while mixing. Mix the two components together for several minutes. Remove all traces of powder from the sides and bottom of the container and keep mixing until it is perfectly blended. Never carry out this operation manually. Use a low-speed mixer (to avoid air being dragged in) or a mortar mixer, which is generally supplied with 25
